Important: Some applications, such as Calendar, work only with the primary Google account
(the first Google account set up with your device). If you plan to use more than
one Google Account with your device, be sure to sign into the one you want to
use with such applications first. When you sign in, your contacts, Gmail
messages, Calendar events, and other information from these applications and
services on the Web can be synchronized with your device. You will be prompted
to sign in or to create a Google Account the first time you start an application that
requires one, such as Gmail or Android Market.
